Description
Technical field
The present invention relates to a kind of hydraulic camshaft adjustment equipment of vane room type, with stator and concentrically and fixed
The sub internal rotor arranged in a manner of it can rotate, wherein, for preventing rotor fixed with relative stator in other words with stator
The locking system of rotation between component is axially arranged between rotor and stator, so that the locking element of locking system
It is sealed (Formschluss) to set up the shape that rotor relative stator is forbidden to rotate.With using spike or pin-shaped locking
The hydraulic camshaft adjustment equipment of the vane room type of the locking system of element is fully disclosed.
Background technology
Here, usually rotor resists the position for being locked in rotor blade in relative rotation and leaning with stator of relative stator
In or be locked in intermediate lock position, that is, following location, blade is between its final position in this position.
Unfortunately, due to its specific method of operation, locking bolt or lock pin build especially big in the axial direction,
And the relatively large number of axial arrangement space of entire camshaft adjuster is used.But the structure space is limited.But
Bolt needs minimum dimension about locking depth, so as to reliably locking.This sets camshaft adjuster/camshaft adjusting
Standby axial length is equally unfavorable.The system also is subjected to very big power in load conditions, this then to need to expend
Measure.In addition, disadvantageously, the manufacture of part is also relatively expensive.
Invention content
The shortcomings that the task of the present invention is offer remedial measure and avoiding in the prior art.Especially, which is
Realize a kind of locking system, which is cost optimization in its manufacture view, needs component as few as possible and uses up
Pipe so can still transmit very big power.It should also be as to realize the axial direction of reduction camshaft adjuster/camshaft adjustment device
Structure space.A kind of intermediate locking system should can be especially realized, wherein as much as possible without rotor fixed stop with regard to energy
It deals with.
For such hydraulic camshaft adjuster or such camshaft adjustment device, the task according to
The present invention solves in the following way, that is, locking element is constructed according to the type of plate.
In the case of application plate shape/plate locking element, rotor is when needed relative to stator locking with anti-rotation.Such as
Fruit applies multiple locking elements in a manner of logically associated each other, then when needed can be medially relatively fixed by rotor
Sub- locking is with anti-rotation.Realize one kind especially section space-efficient embodiment of locking element.
It is therefore advantageous that be configured to plate locking element tool there are two (it is substantially flat, be preferably parallel to each other extension
) side/side, which is connected with each other on outer profile, wherein, such as be configured to ellipsoid in locking element and lack or segment
In the case of, the outer profile of locking element be configured to indent, evagination/dome shape, it is flat or have rill.If locking is first
Part is configured to ellipsoid and lacks or segment, then particularly selects following segment, locking element is realized from receiving by the segment
In its holder equably, low friction and interference-free produce.As a result, but also sealing becomes easy.Such as in locking
In the case of the segment of element, outer profile is implemented into dome shape/evagination.The outer profile of dome shape is characterized by having with two
The shape of a dimension rounding perpendicular to one another.
In order to realize the friction free relative rotation between stator and rotor in the case of undesirable locking, favorably
, locking element is fitted into the case of being connected to spring element in centre in blind hole, wherein, blind hole is arranged on the end side of rotor
Or on the end side of the facing rotors in the fixed component of relative stator, which is, for example, the lid being fastened on stator.
At this it is particularly advantageous that the blind hole for accommodating spring element is introduced into rotor or introducing independently of rotor,
In the receiving sleeve being connected under operating status with rotor.But in the case of both variant schemes, hence it is evident that advantageously, locking
Element, which is installed to, to be introduced into the blind hole in rotor, wherein, which can be structured as drilling.It can certainly be further by blind hole
Through-hole is configured to, it is similary as drilling, but the oily circuit of internal rotor is at this moment must take into consideration, so as not to be damaged to it.
In order to reliably accommodate spring element, it is advantageous to which blind hole has spring element receiving section, example in bottom
Such as recessed portion, spring element is at least partly supported in the recessed portion.Blind hole preferably has the recessed portion of rectangular-shape in bottom,
The spring element independently of rotor designed is at least partly placed in the recessed portion.It can certainly select cube-shaped recess
Portion, but theoretically the rectangle of the bottom surface of recessed portion is advantageous, because it can particularly simply install and ensure very big
Design freedom.
A kind of advantageous embodiment is further characterized in that locking element is scarfed to relative stator in a manner of anti-rotational and fixed
Component, the end side that rotor is scarfed in the recess portion that for example covers or in a manner of anti-rotational recess portion in.Here, two kinds
The first in variant scheme is also particularly suitable.A kind of improvement project is further characterized in that, recess portion has a U-shaped or horse
The outer profile (wherein, side is connected with each other) and/or concave bottom of horseshoe-shaped are obliquely or liftable (angestellt) prolongs
Extend to the surface of the fixed component of relative stator or the end side of rotor.It due to this inclination or lifts, can obtain very well
Shape it is sealed.
In addition appropriately, there are at least two locking elements, to realize intermediate locking.It is possible thereby in view of the modern times
The requirement of the raising of internal combustion engine.
If locking element and corresponding spring element are arranged in such a way the hole for two components in setting respectively
In, that is, make the axial movement of at least part of locking element or pivot that corresponding spring element is attached troops to a unit, so as to hinder
The rotation of rotation stop in each direction, then backstop of the blade on stator can be abandoned.
Also advantageously, there are locking system and/or in the identical or opposite of rotor on each end side of rotor
Side on there are two or more locking systems.Then, the particularly efficient utilization to axial arrangement space is realized.May be used also
So that maintenance and assembling become easier to.
When spring element is preferably configured to lath, spiral compression spring, rubber element, raw rubber element or the elasticity of bending
During volume elements part, cost can be reduced.
Therefore, it is a kind of novel method that segment, which is arranged for preventing the rotation of rotor relative stator in structure, and
And lead to improved hydraulic camshaft adjustment equipment.The rotor assembling of camshaft adjustment device in the stator, and passes through two
Disk or lid axial closing.Rotor in itself in, there are recessed portions on end side, and the locking element of segment type is together with spring element
Part is placed in the recessed portion.Recessed portion is dimensionally embodied as segment being made to sink in recessed portion completely in assembly disk/lid, and
With rotor or the planes align of disk/lid.Thus spring element is tensioned in this position.
In disk, there is the slope shape recessed portion with unilateral stop surface on the position of restriction.If now by rotor
It is rotated relative to stator and relative to the disk being fastened on stator, then segment is equally moved relative to disk and stator.If
The segment reaches recessed portion, then slope of the spring element in recessed portion relaxes.That is, segment snap to it is recessed
Prevent in concave portion and therefore the further rotation of rotor.If rotor is opposite with rotation direction before now to move, then
Segment follows slope and spring element is pre-tensioner again.Therefore rotor unlocks again.It can also be by rotor again by hydraulic pressure
Mode (by oil pressure/oil) unlocks.
It is integrated with one or more fixed stop portions for rotor in the stator, these fixed stop portions limit two and match
The rotation possibility of component.If rotor is guided in fixed stop portion now, then can lock rotor completely by segment
It is fixed.Then, it is not possible to rotate.
In order to which hereafter whole system can be unlocked again, it is necessary to oil pressure is loaded to segment from lid side, to make segment again
It is secondary to be pushed back in recessed portion.Rotor becomes freely and can rotate again as a result,.
If realize the intermediate locking system with two or more locking elements, then must slightly carry out modification.
Because segment usually always can only prevent to rotate, and in centre position in one direction, segment must not have it
Work in the case of his fixed stop portion, thus must by inversely to supporting arrangement in a manner of (in
Anordnung) at the same use at least two segments.Because in this way for each segment, a rotation direction can be with barred, institute
It is a kind of effective feasibility with this.
Once two segments are all by clamping lock, then rotor barred and is fixed position in both rotational directions.In
It is in order to which whole system can unlock again, it is necessary to oil pressure is loaded to segment from an end side and/or the lid side of another side, with
Just segment is made to be pushed back again in corresponding recessed portion.Rotor becomes freely and can rotate again as a result,.
Two segments can be mounted on side on identical blade, be installed oppositely on identical blade, in difference
On blade or opposite install.They can also be mounted on rotor bearing diameter the same side on or opposite one another
Installation.
For function advantageously, segment is located on identical reference circle, this is because otherwise will have different peripheral forces
It works.
Locking element in principle can be located at bearing diameter except or within.
